5.6. Output connections
The OUTPUT section of the rear panel is equipped with Speakon
connectors and
screwable terminals.
If STEREO mode is used, the channel 1 input signal will be output from channel 1 via
terminals 1+ and 1-, and the channel 2 input signal will be output from channel 2
similarly. Bear in mind that if you want to work in stereo, when activating the crossover
filter, you will need two eLPA-350 amplifiers, one for the left signal (L) and the other for
the right signal (R), each of them working with low frequencies in channel 1 and high
frequencies in channel 2.
PARALLEL mode delivers the same input signal to both output channels. If the
crossover filter is activated, channel 1 will work with low frequencies, and channel 2
with high frequencies.
When you want to use the amplifier in bridge mode (BRIDGE), you must set the
"MODE" switch to BRIDGE. The input signal connection will be made through the
channel 1 connector and the output to the loudspeaker via terminals 2+ and 2- of the
Speakon
"CH1" connector or the red CH1+, CH2+ screwable terminals. Bridge mode
bypasses the crossover filter, so it will not affect the signal.
Before starting up the amplifier, make sure that the overall impedance of the set of the
loudspeakers connected to the amplifier (working in BRIDGE mode) is not less than 8
.
The connecting cable between the amplifier outputs and the loudspeakers should be of
high quality, of sufficient cross-section and of the shortest possible length. This is
especially important when the distances to be covered are large: up to 10 meters a
section of not less than 2.5 mm
2
is recommended and not less than 4 mm
2
for longer
distances.
Below is the connection diagram of the eLPA2-350 amplifier depending on the
operating MODE: STEREO, PARALLEL and BRIDGE.
